Corki
Missile Barrage
Now fires a Big One every 3rd missile instead of every 4th
Missile charge rate reduced to 12/10/8 seconds from 12

Karma
These changes to Karma include several quality of life improvements and enhance her ability to generate multiple Mantras in well-executed fights.

Gathering Fire
Mantra cooldown reduction increased to 2 seconds at all levels from 1/1.5/2
Inner Flame
The detonation area now occurs at the actual point of missile impact instead of at the center of the initial target that is hit
Focused Resolve
Mana cost reduced to 70/75/80/85/90 from 70/80/90/100/110
Now applies Gathering Fire's effect on each instance of damage dealt instead of only once on initial application, but now deals damage 3 times over the duration instead of 6
Inspire
Movement Speed duration increased to 1.5 seconds from 1.25
Fixed a bug where the tooltip stated the shield was 80/115/150/185/220 instead of its actual value of 80/120/160/200/240
Mantra Bonus - Defiance
Movement Speed bonus is now always 60% instead of 20/30/40/50/60% (based on Inspire's current rank)
Ally shield / haste range increased to 700 from 600

Kayle
Previous to these changes, Kayle's support spells could often be cast completely off-screen from her opponents. With these reduced ranges, it should be easier for opponents to anticipate her presence in fights.

Lux
On top of her long range and wide array of defensive utility, Lux was also among the fastest ranged champions in the game. These changes force Lux to be more mindful of her timing and positioning as opponents now have more opportunities to capitalize on her mistakes.

Quinn
Harrier
Valor now marks targets slightly more frequently
Targets are now marked more immediately when Valor lands on the target
Vault
Quinn now lands closer to her target when using Vault from far away

Volibear
Volibear was both an extremely powerful duelist as well as an almost guaranteed initiator for early skirmishes. In order to preserve his presence as a threatening fighter, these changes instead reduce Volibear's ability to force engagements early on.
